Miami wakes up to a hot, stormy Monday with a high near 90°F and showers and thunderstorms likely after 11 AM ET — get outdoor plans done early, because the National Weather Service in Miami says heat index values will climb to 103-108°F this afternoon on top of the downpours.
Today’s Setup
Mornings stay mostly dry with some sun, but the Miami forecast office’s Area Forecast Discussion flags a slow-moving mid-level low parked over Georgia steering scattered to numerous storms across the east coast and interior through tonight. A light sea breeze will trigger storms rather than push them along, so the risk today is high rainfall rates combined with slow storm motion — meaning localized flooding is possible in east coast metro areas like Brickell, Little Havana, and coastal Miami Beach. Expect a tenth to a quarter inch of rain, more under any lingering cell.
Best Window To Be Outside
Get out between sunrise and 11 AM for dry pavement — a Key Biscayne beach walk or Coconut Grove jog beats the afternoon storms. After that, plan to be near shelter, whether a Wynwood coffee shop or your own porch, since south winds at only 7 to 10 mph won’t move slow-training storms along quickly.
Rain, Wind, And Flood Risk
No severe watches are in play today, but the flooding angle is real given the rain rates. Keep a waterproof document bag handy near the marina or Biscayne Bay, and avoid lingering in flood-prone underpasses during the heaviest bursts.
What To Wear Or Bring
With heat index near 105°F, go breathable and quick-dry: quick dry swim trunks or a women’s swimsuit under regular clothes for beach-adjacent plans, and men’s sport sandals that dry fast between downpours. For sun and rain days ahead, browse our outdoor gear deals, including the UPF 50+ sun hoodie for anglers squeezing in trips between storms.
Game Day And Concert Watch
Inter Miami CF hosts Atlético de San Luis in the Leagues Cup Wednesday, August 5 at Nu Stadium, and the Miami Marlins face the Los Angeles Angels Friday, August 7 at LoanDepot Park — get tickets on SeatGeek or find tickets on StubHub, and grab official team gear on Fanatics beforehand. Music fans should mark Tuesday, August 6 for Mumford & Sons at Hard Rock Live — look for a Mumford & Sons t-shirt for the show.
Tonight’s Dinner Idea
Heat index this high means skip the stove: a cold Thai noodle salad or build-your-own wrap bar keeps the kitchen cool, and a high-powered blender turns extra fruit into smoothie bowls for tomorrow. Keep drinks cold with an insulated tumbler 30oz. Need ingredients? You can order groceries on Amazon and have everything delivered to your door.
Next Few Days
Tuesday looks similar, high near 89°F with a 50% chance of afternoon storms, while Tuesday night coverage jumps to 70% as the stalled front washes out and high pressure builds in from the Atlantic. Expect the same rhythm into midweek — sunny mornings, stormy afternoons, heat index near the low 100s. Check our Miami weather forecast page for updates.
